Abstract:
In some example embodiments, a method includes performing a memory scrub of a memory across a scrub cycle of multiple scrub cycles. The method includes identifying correctable errors of symbols in the memory that are a result of accesses from a section of the memory in response to the memory scrub. The method also includes performing an analysis across the multiple scrub cycles, wherein the performing of the analysis comprises determining whether at least two symbols across the multiple scrub cycles have at least one correctable error. The method includes responsive to determining that at least two symbols across the multiple scrub cycles have at least one correctable error, executing at least one repair of the memory that includes the section of memory.
